Deck Bench Plans

These deck bench plans are easy to follow and can be adjusted to fit your
size needs. The length of this bench is 3 feet, but can be extended up
to 6 feet without changing the basic design.

Assembled Deck Bench

The width of this bench is 20 1/2 inches wide so that three 2x6s will fit
inside the bench framing with a little spacing between boards. This
assumes that you are using milled lumber where a 2x6 is actually 1 5/8
inches by 5 5/8 inches.

Here's the math; if the width of the framing is 1 5/8 inches and the
outside dimension is 20 1/2 inches, then the inside dimension will be 3
1/4 inches less, or 17 1/4 inches.

Three 2x6s (with an actual width of 5 5/8 inches) added
together is 16 7/8. 17 1/4 inches minus 16 7/8 inches is 3/8 of an
inch. This is the room you will have for spacing between the 2x6s.

Deck Bench Plans - Assembly

Cut the 4 legs of the deck bench @ 16 inches long. Notch the
ugly end of each leg as shown below. If you are using a circular
saw, you can set the depth of the blade to 1 5/8 inches and cut straight
through on two sides of the leg.

When making the other two cuts, you will need to chisel the last part
of the cut, since the circular blade won't cut all the way through.

Cut the four pieces of the frame, beveling each end cut. Assemble
the 4 pieces together using 2.5 inch galvanized deck screws. Once
assembled, attach the four legs using four deck screws. (see below)

Once the four legs have been attached, flip the deck bench over upright
and attach the three 2x4 framing members using the 2.5 inch galvanized deck
screws.

Cut the three 2x6 boards for the bench seat. It is best to measure
the actual opening to get the length of these boards. It should be
approximately 32 3/4 inches.

Place the three boards inside the bench framing and space them evenly
apart. Once the spacing has been determined, secure each bench
seat board to the 2x4 framing with the 2.5 inch galvanized deck screws.

Choosing Lumber

I have built this bench using Western Red Cedar and Redwood. I
generally use pressure treated lumber for the parts that you can't see
(like the 2x4s in this deck bench plans).

The best way to preserve your new bench is to seal it with a
stain/sealer of your choice. I have used different brands and
don't really have a preference.
